DOOR-OPENER.

SPECIFICATION formingpart of Letters Patent No. 792,989, dated June 20, 1905.

Application filed November 8, 1904. Serial No. 231,902.

To all whom, it Ina/7 concern:

Be it known that we, JOHN B. Hoorns and CHARLES H. MARRIOTT, citizens of the United States, residing at Latrobe, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Door-Openers; and wedo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. V

This invention relates to doors, and more particularly to openers therefor, and has for its object to provide a mechanism by means of which a door may be opened and which will be arranged for operation by the weight of a person or object.

A further object is to provide a mechanism which will be simple and cheap, which will operate easily, and which will not be liable to become deranged.

Other objects and advantages will be apparent from the following description, and it will be understood that modifications of the specific construction shown may be made and any suitable materials may be used without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views. Figure 1 is a view showing a door provided with the present invention and illustrating a foot-platform in perspective. Fig. 2 is a sectional view of the flooring, illustrating the operating mechanism in elevation. Fig. 3 is a section on line 3 3 of Fig. 1 and illustrating a portion of the mechanism as seen at right angles to Fig. 2. Fig. 4 is asectional view of a modified form of the invention. Fig. 5 is a top plan View of a portion of the operating mechanism, partly in section.

Referring now to the drawings, there is shown a door 5 of the usual type, to the outer face of which, adjacent to its lower edge, there is secured a metallic plate 7. At the hinged side of the door this plate is turned at right angles and extends downwardly through an opening 6 in the floor 8 in the form of a rod 9. Below the floor the rod 9 is turned laterally,

as shown at 10, and secured to the free end of this lateral portion there is a cable 11, which is passed over a pulley 12 and is provided with a weight 13 at its free end, the arrangement being such that the door is held normally in closed position by the weight.

Secured to the under side of the floor there is a bracket 14., inwhich there is pivoted a lever 15 of peculiar form. This lever includes a horizontal portion 15, pivoted at one end in the bracket, and extending upwardly from the free end of this portion there is a vertical portion 15". Extending downwardly from the pivoted end of the portion 15' there is a finger 15, which is turned to extend below and parallel with the portion 15. At its free end, which extends laterally .somewhat beyond the outer end of the portion 15, the finger 15 is turned downwardly at a slight angle. upper end of the portion 15 of the lever, and at its other end the link is pivoted to the portion of the rod 9 between the vertical portion of this rod and the free end of the portion 10.

The arrangement of the parts just described is such that when the lever is moved upwardly upon its pivot the door will be opened, as will be readily understood, the link 16 being arranged to move the portion 10 of the rod 9 in a direction opposite to that in which it is moved by the weight 13.

Secured to the floor 8 at a point in front of the door 5 and lying in a plane parallel with the door when the latter is in closed position there is a hanger 17, consisting of a metallic plate secured at its central portion to the floor and having its end portions bent downwardly and lying parallel to each other. Pivoted between their ends to the downwardly-extending portions of the hanger 17 are the spaced legs of a U-shaped member 18, the bight portion of this member having an outwardly-extending projection 19, provided with a longitudinal slot 20, in which is engaged the finger 15, adjacent to its free end. Pivoted to the free ends of the legs of the U-shaped member 18 are upwardly-extending rods 19, which pass through perforations 20 in the A link 16 is pivoted at one end to the floor, these perforations communicating with a recess 21 in the upper face of the floor, and secured to the upper ends of the rods 19 there is a platform 22 of a size to enter the recess 21. This platform 22 lies normallyjust above the level of the floor and is spaced-sufficiently from the door 5 to permit of the latters opening without striking a person or object standing upon the platform 22.

The operation of the mechanism will be obvious. When weight is placed upon the platform 22, the latter will be depressed, and its movement will be communicated to the door to swing the latter upon its hinges. When the weight is removed from the platform, the weight 13 will return the mechanism to its original position.

In Fig. 4 there'is shown a construction in which an additional hanger 23, similar to the hanger 17, is secured to the under face of the floor at the opposite side of the door from the hanger l7, and pivoted in the hanger 23 there is a U-shaped member 24:, similar to the member 18 except for the projection 19, which in this instance is omitted. Rods 25, corresponding to the rods 19, extend upwardly through perforations 26, communicating with a recess 27 in the upper face of the floor and extending beneath the door 5, the openings 20 also communicating with this recess. Secured to the upper ends of the four vertically-extending rods and lying normally above the recess 26 there is a platform 27, and it will be understood that depression of this platform Will cause the door to open. This arrangement permits the door to be opened antomatically from either side.

What is claimed is l. The combination with a door, of a vertically-extending rod secured at one end to the door, the remaining end of the rod being turned laterally, a pulley mounted adjacent to the rod, a cable secured to the free end of the laterally-turned portion of the rod and engaged with the pulley, a weight secured to the free end of the cable, said weight being arranged to hold the door yieldably in closed position, a bracket, a lever pivoted in the bracket. a link pivoted to the lever and to the laterally-turned portion of the rod and arranged for movement of the rod against the action of the weight when the lever is moved in one direction, a hanger, a member pivoted between its ends in the hanger, connections between one end of the member and the lever, for movement of the latter when the member is moved, and .a rod pivoted to the remaining end of the member and extending upwardly, said rod being arranged to receive pressure upon its upper end to operate the member and the lever for movement of the rod against the action of the weight.

2. The combination with a door, of a vertically-extending rod secured at one end to the door, the remaining end of the rod being turned laterally, a pulley mounted adjacent to the rod, a cable secured to the free end of the laterally-turned portion of the rod and engaged with the pulley, a Weight secured to the cable, said weight being arranged to hold the door yieldably in closed position, spaced brackets, a lever including spaced legs, and a connecting-bight, said legs being pivoted intermediate of their ends to the brackets, an outwardly-extending projection carried by the bight and having a longitudinal slot therein, a pivotally-mounted lever, a finger carried by the second lever and .engaged in the slot of the projection for movement of the second lever upon its pivot when the first lever is moved pivotally, a link pivotally connected with the second lever and with the laterally-extending portion of the first-mentioned rod for movement of said rod to operate the door when the link is moved upon its pivot, upwardly-extending rods pivoted to the unattached ends of the spaced legs of the lever, and a footboard secured to the upper ends of the rods.

In testimony whereof We affix our signatures in presence of two witnesses.
